PEDAL-CLUTCH MECHANISM.

SPECIFICATION forming part of Letters Patent No. 660,380, dated October 23, 1900.

Application filed March 6, 1900. Eerial No. 7,507. (No model.)

To all whom it may concern:

Be it known that I, EMILE KLABER, a subject of the Queen of Great Britain, residing in the borough of Manhattan, in the city and State of New York, have invented a new and useful Improvement in Pedal-Clutch Mechanism for Mechanically-Operated Musical Instruments, of which the following is a specification.

My invention is particularly designed and adapted for the purpose of communicating, from the reciprocating motion of a pair of pedals, continuous rotary motion to the powerdr-um which actuates the mechanism of me-' chanically-operated musical instruments.

To this end I employ clutch-pulleys fixed on a shaft, which may be the drum-shaft or an intermediate shaft connected therewith, said clutch-pulley receiving continuous rotation by the action of friction-clutches mounted loosely on the shaft and actuated alternately by the pedals through strap-and-pulley connections, as hereinafter described.

In the accompanying drawings, Figure 1 is a front View of the device. Fig. 2 is a side view thereof, showing parts of the frame and shafts in section. Fig. 3 is a transverse section of one of the clutch-pulleys.

6 6 represent a pair of pedals hinged at their front ends 7 and connected at back by pull-straps 8 8 with the clutch mechanism in the following manner: The pull-strap 8 is coiled around and attached at its end to a pulley 9, keyed on a rock-shaft 10, on which is also keyed a pulley 11, on which is coiled and fixed the end of a belt 12, which is carried down and coiled around a clutch-sleeve 13, and thence upward to a spring-pulley 14, on which its end is coiled and fixed, so that the said spring-pulley will pay out the belt in the active movement thereof, (indicated by the arrows,) produced by the depression of the pedal 8, and when the pedal is released will take up the slack and restore the parts to normal position. The pull-strap 8 operated by the pedal 6, is coiled and fixed on a double.

pulley 15 16, running loosely on the shaft 10 and confined in position by a collar 17, keyed thereon. On the part 16 of the said loose pulley is coiled and fixed the end of a belt 18,which is carried down and coiled around a second clutch-sleeve 19, and thence upward to a spring-pulley 20, on which its end is coiled and fixed, so that said spring-pulley will pay out and take up slack in the reciprocating movement of the pedal 6 and its connections, as already described with reference to the pedal 6 and connections. The helical springs of the pulleys 16 and 20 areshown at 21.

The clutch-sleeves 13 and 19 carry clutcheccentrics 22,0f similar and common construca tion, one of which is shown in Fig. 3. These eccentrics, together with their operating sleeves, turn loosely on the shaft 23 of the motor-drum 24 and impart continuous rotation to said drum through the medium of friction-clutch balls 25, engaging with clutch-pulleys 26 26, keyed on said shaft 23. The shaft is also provided with a fly-wheel 27.

The continuously-rotating drum 24 actuates the jack-rods 28 of the respective hammers (not shown) through the medium of friction-toes 29, held normally out of contact with the drum and dropped into engagement therewith by the passage of the note-apertures in the moving tune-sheets in a well-known manner.

The following is what I claim as new and desire to secure by Letters Patent:

1. In a mechanically-played musical instrument the combination of an operating-pedal, means for transmitting reciprocating motion therefrom, friction clutch mechanism converting the reciprocating motion into continuous rotary motion the power-drum 24 deriving continuous rotation from said clutch mechanism and friction-toes 29 actuated by the drum 24, substantially as set forth.

2. A pedal-clutch mechanism for driving the motor-drum of a mechanically-operated musical instrument, comprising pedals 6, 6

pull-straps 8, 8 pulleys 9, 11, 15, 16, shaft 10, belts 12, 18, clutch-sleeves 13, 19, eccentric clutches 22, and clutch-pulleys 26, 26 on the shaft 23 of motor-drum 24, substantially as described.
